[Congenital radial head dislocation on both sides].

Both traumatic and congenital dislocation of the radial head are very rare in childhood. It can sometimes be difficult to tell them apart in practice. In this paper therefore, we present one case and discuss the various aspects of both conditions with reference to the available literature. Traumatic dislocation of the radial head is generally easily reduced without open surgery, and an open procedure is virtually never indicated in a patient who is still growing. In contrast, specific treatment of congenital radial head dislocation is not necessary because most patients are free of pain.
